Using default values for stored procedure parameters

    Hi,

    I have been trying to use default values as parameters of a stored procedure.

    All the explanations tell about using a NULL value for a procedure parameter to make it optional.

    I have also read that any value that is compatible with the datatype of the parameter could have been set.

    Following is what I am trying to do:

    ------------------------------------

    create procedure Proc_Def_Param

    @startDate datetime = NULL,

    @endDate datetime = getdate() ------------------ I

    As

    Begin

    .....

    .....

    End

    ------------------------------------

    However I am unable to parse this code. The error says:

    "Incorrect syntax near '('."

    which takes me to line I marked above.

    The same proc parsed when I put in actual date. Eg '12-26-07'

    Could anyone guide me on supplying default values to a stored procedure.

    Is it possible to provide only explicit values to the stored procedure's default parameters?

    Thank you.

    You can't assign a non-deterministic value as the default parameter like that. Instead, assign it something like NULL, and then inside the stored procedure, set it to Getdate() if it's currently set to NULL.
